Cilia and flagella
The structures allow the cell to perform specific functions.
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.
The special structures in the cell membrane that allow materials like water and sugar to pass through are proteins called transport proteins. These proteins help facilitate the movement of specific molecules across the membrane by acting as channels or carriers. They play a crucial role in regulating the flow of substances in and out of the cell.
Two structures that could propel a eukaryotic microorganism are flagella and cilia. Flagella are long, whip-like appendages that help with cell movement by propelling the organism forward. Cilia, on the other hand, are shorter and more numerous hair-like structures that also aid in movement by beating in a coordinated manner. Both structures contain microtubules and motor proteins that allow for movement through the surrounding fluid.

Cell movement involves structures such as the cytoskeleton, which includes microfilaments, microtubules, and intermediate filaments, that provide support and allow for cellular movement. Cell adhesion molecules such as integrins play a role in interactions between cells and the extracellular matrix, facilitating cell migration. Additionally, motor proteins like myosin and dynein generate force to drive cell movement by interacting with the cytoskeletal components.
things
Flagella are external structures that propel cells. The cytoskeleton (I believe actin and myosin are the components of the cytoskeleton responsible for movement, but I'm not sure) is an internal structure that facilitates movement by changing the shape of the cell.
movement
no, there can be a possible mutation but nothing major. there is movement inside the cell though.
These special structures are called protein gates or protein channels. Water is able to diffuse through the cell membrane since it is a small molecule. However, there are channels called aquaporins that allow water to enter the cell. A glucose molecule cannot just diffuse into a cell. There are glucose channels on the surface of the cell membrane that bind glucose molecules and allow them to enter the cell.
In a Prokaryotic cell, these structures are the flagella.
